[ repository copy of sys/pci/pci_ioctl.h to sys/sys/pciio.h happened in the
background ] Rename sys/pci/pci_ioctl.h to sys/sys/pciio.h to make it easier for userland programs to use this interface. Reformat the file, and add a BSD-style copyright to it. Add a new man page for pci(4). The PCIOCGETCONF, PCIOCREAD, and PCIOCWRITE ioctls are documented, but the PCIOCATTACHED ioctl is not documented because it is not implemented. Change includes of <pci/pci_ioctl.h> to <sys/pciio.h> or remove them altogether. In many cases, pci_ioctl.h was unused. Reviewed by: steve

.Sh NAME
|
||||
.Nm pci
|
||||
.Nd Generic PCI driver
|
||||
.Sh SYNOPSYIS
|
||||
.Cd controller pci0
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm pci
|
||||
driver provides a way for userland programs to read and write
|
||||
.Tn PCI
|
||||
configuration registers. It also provides a way for userland programs to
|
||||
get a list of all
|
||||
.Tn PCI
|
||||
devices, or all
|
||||
.Tn PCI
|
||||
devices that match various patterns.
|
||||
.Pp
|
||||
Since the
|
||||
.Nm pci
|
||||
driver provides a write interface for
|
||||
.Tn PCI
|
||||
configuration registers, system administrators should exercise caution when
|
||||
granting access to the
|
||||
.Nm pci
|
||||
device. If used improperly, this driver can allow userland applications to
|
||||
crash a machine or cause data loss.
|
||||
.Sh KERNEL CONFIGURATION
|
||||
It is only necessary to specify one
|
||||
.Nm pci
|
||||
controller in the kernel. Additional
|
||||
.Tn PCI
|
||||
busses are handled automatically as they are encountered.
|
||||
.Sh IOCTLS
|
||||
The following
|
||||
.Xr ioctl 2
|
||||
calls are supported by the
|
||||
.Nm pci
|
||||
driver. They are defined in the header file
|
||||
.Aq Pa sys/pciio.h .
|
||||
.Bl -tag -width 012345678901234
|
||||
.Pp
|
||||
.It PCIOCGETCONF
|
||||
This
|
||||
.Xr ioctl 2
|
||||
takes a
|
||||
.Va pci_conf_io
|
||||
structure. It allows the user to retrieve information on all
|
||||
.Tn PCI
|
||||
devices in the system, or on
|
||||
.Tn PCI
|
||||
devices matching patterns supplied by the user.
|
||||
The
|
||||
.Va pci_conf_io
|
||||
structure consists of a number of fields:
|
||||
.Bl -tag -width match_buf_len
|
||||
.It pat_buf_len
|
||||
The length, in bytes, of the buffer filled with user-supplied patterns.
|
||||
.It num_patterns
|
||||
The number of user-supplied patterns.
|
||||
.It patterns
|
||||
Pointer to a buffer filled with user-supplied patterns.
|
||||
.Va patterns
|
||||
is a pointer to
|
||||
.Va num_patterns
|
||||
.Va pci_match_conf
|
||||
structures. The
|
||||
.Va pci_match_conf
|
||||
structure consists of the following elements:
|
||||
.Bl -tag -width pd_vendor
|
||||
.It pc_sel
|
||||
.Tn PCI
|
||||
bus, slot and function.
|
||||
.It pd_name
|
||||
.Tn PCI
|
||||
device driver name.
|
||||
.It pd_unit
|
||||
.Tn PCI
|
||||
device driver unit number.
|
||||
.It pc_vendor
|
||||
.Tn PCI
|
||||
vendor ID.
|
||||
.It pc_device
|
||||
.Tn PCI
|
||||
device ID.
|
||||
.It pc_class
|
||||
.Tn PCI
|
||||
device class.
|
||||
.It flags
|
||||
The flags describe which of the fields the kernel should match against.
|
||||
A device must match all specified fields in order to be returned. The
|
||||
match flags are enumerated in the
|
||||
.Va pci_getconf_flags
|
||||
structure.
|
||||
Hopefully the flag values are obvious enough that they don't need to
|
||||
described in detail.
|
||||
.El
|
||||
.It match_buf_len
|
||||
Length of the
|
||||
.Va matches
|
||||
buffer allocated by the user to hold the results of the
|
||||
.Dv PCIOCGETCONF
|
||||
query.
|
||||
.It num_matches
|
||||
Number of matches returned by the kernel.
|
||||
.It matches
|
||||
Buffer containing matching devices returned by the kernel. The items in
|
||||
this buffer are of type
|
||||
.Va pci_conf ,
|
||||
which consists of the following items:
|
||||
.Bl -tag -width pc_subvendor
|
||||
.It pc_sel
|
||||
.Tn PCI
|
||||
bus, slot and function.
|
||||
.It pc_hdr
|
||||
.Tn PCI
|
||||
header type.
|
||||
.It pc_subvendor
|
||||
.Tn PCI
|
||||
subvendor ID.
|
||||
.It pc_subdevice
|
||||
.Tn PCI
|
||||
subdevice ID.
|
||||
.It pc_vendor
|
||||
.Tn PCI
|
||||
vendor ID.
|
||||
.It pc_device
|
||||
.Tn PCI
|
||||
device ID.
|
||||
.It pc_class
|
||||
.Tn PCI
|
||||
device class.
|
||||
.It pc_subclass
|
||||
.Tn PCI
|
||||
device subclass.
|
||||
.It pc_progif
|
||||
.Tn PCI
|
||||
device programming interface.
|
||||
.It pc_revid
|
||||
.Tn PCI
|
||||
revision ID.
|
||||
.It pd_name
|
||||
Driver name.
|
||||
.It pd_unit
|
||||
Driver unit number.
|
||||
.El
|
||||
.It offset
|
||||
The offset is passed in by the user to tell the kernel where it should
|
||||
start traversing the device list. The value passed out by the kernel
|
||||
points to the record immediately after the last one returned. The user may
|
||||
pass the value returned by the kernel in subsequent calls to the
|
||||
.Dv PCIOCGETCONF
|
||||
ioctl. If the user does not intend to use the offset, it must be set to
|
||||
zero.
|
||||
.It generation
|
||||
.Tn PCI
|
||||
configuration generation. This value only needs to be set if the offset is
|
||||
set. The kernel will compare the current generation number of its internal
|
||||
device list to the generation passed in by the user to determine whether
|
||||
its device list has changed since the user last called the
|
||||
.Dv PCIOCGETCONF
|
||||
ioctl. If the device list has changed, a status of
|
||||
.Va PCI_GETCONF_LIST_CHANGED
|
||||
will be passed back.
|
||||
.It status
|
||||
The status tells the user the disposition of his request for a device list.
|
||||
The possible status values are:
|
||||
.Bl -ohang
|
||||
.It PCI_GETCONF_LAST_DEVICE
|
||||
This means that there are no more devices in the PCI device list after the
|
||||
ones returned in the
|
||||
.Va matches
|
||||
buffer.
|
||||
.It PCI_GETCONF_LIST_CHANGED
|
||||
This status tells the user that the
|
||||
.Tn PCI
|
||||
device list has changed since his last call to the
|
||||
.Dv PCIOCGETCONF
|
||||
ioctl and he must reset the
|
||||
.Va offset
|
||||
and
|
||||
.Va generation
|
||||
to zero to start over at the beginning of the list.
|
||||
.It PCI_GETCONF_MORE_DEVS
|
||||
This tells the user that his buffer was not large enough to hold all of the
|
||||
remaining devices in the device list that possibly match his criteria. It
|
||||
is possible for this status to be returned, even when none of the remaining
|
||||
devices in the list would match the user's criteria.
|
||||
.It PCI_GETCONF_ERROR
|
||||
This indicates a general error while servicing the user's request. A more
|
||||
specific indication of the problem may or may not be printed in the kernel
|
||||
message buffer (and by implication, the system console).
|
||||
.El
|
||||
.El
|
||||
.It PCIOCREAD
|
||||
This
|
||||
.Xr ioctl 2
|
||||
reads the
|
||||
.Tn PCI
|
||||
configuration registers specified by the passed-in
|
||||
.Va pci_io
|
||||
structure. The
|
||||
.Va pci_io
|
||||
structure consists of the following fields:
|
||||
.Bl -tag -width pi_width
|
||||
.It pi_sel
|
||||
A
|
||||
.Va pcisel
|
||||
structure which specifies the bus, slot and function the user would like to
|
||||
query.
|
||||
.It pi_reg
|
||||
The
|
||||
.Tn PCI
|
||||
configuration register the user would like to access.
|
||||
.It pi_width
|
||||
The width, in bytes, of the data the user would like to read. This value
|
||||
may be either 1, 2, or 4. 3-byte reads and reads larger than 4 bytes are
|
||||
not supported.
|
||||
.It pi_data
|
||||
The data returned by the kernel.
|
||||
.El
|
||||
.It PCIOCWRITE
|
||||
This
|
||||
.Xr ioctl 2
|
||||
allows users to write to the
|
||||
.Tn PCI
|
||||
specified in the passed-in
|
||||
.Va pci_io
|
||||
structure. The
|
||||
.Va pci_io
|
||||
structure is described above. The limitations on data width described for
|
||||
reading registers, above, also apply to writing
|
||||
.Tn PCI
|
||||
configuration registers.
|
||||
.El
|
||||
.Sh FILES
|
||||
.Bl -tag -width 01234567890 -compact
|
||||

.Sh HISTORY
|
||||
The
|
||||
.Nm pci
|
||||
driver (not the kernel's
|
||||
.Tn PCI
|
||||
support code) first appeared in
|
||||
.Fx 2.2 ,
|
||||
and was written by Stefan Esser and Garrett Wollman.
|
||||
Support for device listing and matching was re-implemented by
|
||||
Kenneth Merry, and first appeared in
|
||||
.Fx 3.0 .
|
||||
.Sh AUTHORS
|
||||
.An Kenneth Merry Aq ken@FreeBSD.ORG
|
||||
.Sh BUGS
|
||||
It isn't possible for users to specify an accurate offset into the device
|
||||
list without calling the
|
||||
.Dv PCIOCGETCONF
|
||||
at least once, since they have no way of knowing the current generation
|
||||
number otherwise. This probably isn't a serious problem, though, since
|
||||
users can easily narrow their search by specifying a pattern or patterns
|
||||
for the kernel to match against.
